GAS-BURNING- ATTACHMENT FOR FURNACES.

Specification of Letters Patent.

Application filed March '7, 1908.

Patented Sept. 22, 1908.

Serial No, 419,678.

To all whom it may concern.'

Be it known that I, GLEN G. WEINMAN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Gas-Burning Attachments for Furnaces, of which the following is a speciiication.

The principal object of this invention, among others, is to provide a gas burner adapted for ready attachment to the ordinary doorway of a furnace originally designed for the consumption of coal, so that no expensive alterations need be made to convert such furnace into onefor the consumption of gas.

The invention is especially adapted to fill a want in those regions where natural gas in abundance has been discovered and by its comparative cheapness, cleanliness and cone venience renders it necessary or profitable either to install a new furnace adapted to the consumption of gas, or to convert the old coal burning furnace into one adapted to such new fuel. To install a new furnace is highly expensive and to make the changes in an old one, as heretofore proposed, was

. costly and troublesome.

The invention is exemplified in the construction herein shown and described, the invention not being confined to the particular form of the parts shown.

In the accompanying drawings-Figure l is a vertical sectional view on the line -x Fig. 2 showing some parts in full 3 Fig. 2 is a front view with parts broken out to illustrate details.

In the views 3 designates a plate that is to be secured in a suitable manner over the opening where `the usual door is provided. This plate is made with an opening 3 that has secured in it, by rivets 4a, a hollow thimble-like open frame 4 of rectangular form and having its inner front edges bent or turned inward in the form of a lip as seen at 4b to stand across the spaces between the hinged edges of the deiiecting plates (hereinafter described) and the outer end of the thimble and thereby insure the entrainment of air between the inner sides of said plates and prevent it from passing between the outer sides of said plates and the Walls of the thimble. Hinged to several ears, as seen at 4C, in the upper and lower cavities at the front of the frame 4 are two plates 5 and 6, respectively, each of which is capable, independently of the other, of being swung up or down in that portion of the frame 4 which projects into the furnace. The vertical walls of the thimble close the spaces between the side edges ofthe deflector plates and coniine or direct the fuel to pass between the inner edges of said plates. Pivoted to each of the plates on ears, as seen at 5L and 6a, is a curved rack arm, as seen at '7 and 8, respectively. These rack arms 7 seen at 7a and Sa, respectively, and by means of which the arm can be adjusted, either inward. or outward, and the plate raised or lowered to change its inclination. It will, therefore, be observed that by adjustin the arms 7 and 8 the inner free edges of the p ates 5 and 6 can be moved nearer together or farther asunder. It will also be observed that by suitably elevating both plates from the position shown a flow of gas inward will be deflected upward, and conversely, by suitably lowering both plates, the flow of gas inward would be deflected downward.

9 designates the gas-su ply nozzle. This is referably of horizonta ly elongated form an located parallel to the opening between the plates 5 and 6, and somewhat removed from the plane of the face of the plate 4, so that a suitable quantity of air for admixture with the gas can be entrained with the gas. The fuel is ignited at or near the inner edges of the deflecting plates 5 and- 6 and burns in the lire chamber with varying intensity, according to the quantity of fuel supplied and admixed air. The quantity of fuel supplied through the nozzle can be regulated by an ordinary valve as at 10.

With this invention a steady heat under the boiler can be maintained and thisv heat can be varied and directed with great nicety by adjusting the deflector plates 5 and 6. For example, the issuing name can be directed upward directly against the boiler tubes, or it can be directed away from said tubes, and thus with the saine supply of fuel vary the effecten the boiler.

My invention can be applied to many furnaces originally designed to use coal, it being only necessary to remove the usual iirechamber door and bring in the gas-supply equi ment.

W at I claim and desire to secure by Letters Patent is:

1'. A gas burning attachment for furnaces comprising, in combination, a thimble-like frame 4, open at its front and rear ends, and provided at its front end with an outwardly standing flange whereby it may be attached to a furnace doorway and an inwardly standing lip, deflecting plates hinged, each 'at one of its edges, to the upper and lower edges respectively of the front end of said frame and in rear of said inwardly standing lip, so that the latter shall obstruct the opening between the hinged edges of the delecting plates and the frame, and arms`7 and 8 operatively engaging said deflecting plates respectively, said arms adapted to engage said frame to hold the plates in different positions to which comprising, in combination, a thimble-like frame 4 open at its front and rear ends and provided with means whereby it'may be attached to a furnace door-way, and with an inwardly turned lip 4b at its front or mouth end, deflecting plates 5 and 6 hinged respectively to the upper and lower edges of the front end of said frame, and arms 7 and 8 operatively engaging the ends of said deiiector plates respectively, said arms adapted to engage said frame to hold said deilector plates in dierent positions to which they may be respectively adjusted, substantially as described.
